Embodiment Construction

[0024] The present invention will be further described below. The following examples are only used to more clearly illustrate the technical solutions of the present invention, and cannot limit the protection scope of the present invention with this.

[0025] The present embodiment discloses a method for cultivating black fish fry in paddy fields: comprising the following steps:

[0026] Set up paddy fields and fish ponds alternately, the depth range of fish ponds and paddy fields is 30-100cm, and separate a certain temperature-controlled water area from fish ponds; use isolation nets to separate paddy fields and fish ponds to prevent black fish from swimming into paddy fields; introduce River water, and make the river water level higher than 8-25cm of the paddy field ground. The ratio of rice fields to fish ponds ranges from 1:0.5 to 1:0.8.

[0027] Select the spawning snakehead, and put the spawning snakehead into the fish pond; the spawning snakehead is preferably more tha...

Abstract

The present invention discloses a method for cultivating black fish fry in rice fields. The method comprises the following steps: rice fields and fish ponds are arranged alternately, depth ranges of the fish ponds and the rice fields are 30-100 cm, and certain temperature-controlled water areas are separated in the fish ponds; the rice fields and fish ponds are separated by isolation nets; river water is introduced and river water horizontal plane is 8-25 cm higher than rice field ground; spawning black fish is selected and placed into the fish ponds; fish food is regularly put in the fish ponds; a spawning stimulant is put into the fish ponds; after the spawning black fish spawns, fish eggs are collected; and the collected fish eggs are individually transferred to the temperature-controlled water areas for incubation. The method can increase oxygen content of water in the fish ponds through rice, when weeding is done by artificial weeding, weeds can be used as black fish food. Excrement produced by the black fish can also be used as nutrients for rice seedlings. Due to the fact that the rice fields and fish ponds are arranged alternately, ventilation of the rice fields are more conducive, a wind pollination effect of the rice fields is enhanced, and the unit output of the rice fields is improved.

Description

technical field [0001] The invention relates to the technical field of cultivating fish fry in paddy fields, in particular to a method for cultivating black fish fry in paddy fields. Background technique [0002] Snakefish is a treasure in water and one of the most commonly eaten fish by humans. Since the reproduction of snakehead has strict requirements on the environment, and the survival rate of snakehead eggs in the natural environment is relatively low, artificial intervention must be carried out to the reproduction of snakehead to increase the yield of snakehead. The breeding season of snakehead fish basically coincides with the growth season of rice. Weeds will inevitably appear during the growth of rice, and the reproduction of snakehead fish requires a lot of water-soluble oxygen. Therefore, the combination of paddy fields and blackfish fry cultivation can achieve mutual benefits. . Contents of the invention [0003] In order to solve the deficiencies in the pri...
